I haven't purchased these species yet, but I'm very interested in them. I have a few questions... I know they require different setups. And won't be housed together.
1. Is an 18x18x24 large enough to house more than two frogs for both species?
2. The tanks will be in my basement and an average temp of 55 degrees. Is this to cold for both species?

The main concern is the air temp in my basement. I have really cold winters where the temps in my basement are between 50-58 degrees.
